FLARM and SSR antenna in my Europa. They work fine with plenty of range and n
ot impeded by the fibreglass fuselage.
VHF comm antenna is dip=C3=B4le mounted on the rear fin as per the build man
ual. Again no range problems and all discretely mounted inside the aircraft.

need a ground plane. My research indicates a 12 inch circle of thin copper o

ide the aircraft so things like the engine and other metal stuff doesn

and a GPS and Comm antenna too, but those don=99t seem to need a
ground plane. I am being informed that these antennas need to be at least 4
0 inches apart as well. Also, I have been told that putting the antenna itse
lfoutside the aircraft and the ground plane inside is a bad idea that screws
up the signal.
